Can you please first check the size of that file? There is a file size limit of 1 MB for PHP files on our hosting. From what I can tell, the file contains page templates, which sounds like it could potentially be quite big. If it is too big, you can try to work around it by splitting the PHP file yourself. However, that’s quite a bit of work, requires some understanding of PHP code and is likely to cause problems with upgrades. Since you already have a paid domain name and a paid WordPress theme, maybe it would be good to consider premium hosting as well? If this is a business critical website, premium hosting will help ensure that it’s faster and more reliable than it is on free hosting. And as a bonus for you: there are no file size limits on premium hosting.
